President Obama hosted a reception in honor of Cinco de Mayo in the East Room of the White House yesterday. In his remarks, the President explained how Cinco de Mayo "marks a great moment in Mexican history -- one that ended up shaping the United States as well."

The President made something very clear in his State of the Union address this past January: Wherever and whenever he can take action to expand opportunity for more American families, he's going to do it, with Congress or without.

Yesterday, the White House Photo Office uploaded more than 150 photos from January through March of this year, to give you a behind-the-scenes look at what the President and First Lady have been up to.
